Cartridges & Mechanical Seals

168 RELATED PRODUCTS Face seals These seals are used for sealing in rotating applications in extremely harsh working conditions in which high resistance to wear is required. They are formed by two identical metal rings situated opposite each other through a lapped area in two separate housings. One of the parts remains static in the housing while the other rotates with its housing. The rings are designed in such a way that they open outwards with respect to the seal faces towards the shaft, forming a line (vacuum) in the shape of a cone that has the following benefits: - The lubricant easily reaches the seal faces, due to the capillarity effect and the centrifugal force. - As the wear increases, the face moves forwards toward the central shaft. Con- sequently the seal has considerable wear resistance. The seal is completely worn when the internal diameter is reached. This type of seal is used in many different applications: caterpillar-tracked vehicles such as diggers and bulldozers, heavy trucks, farming machines, tunnel boring ma- chines, mixers, agitators, wind farms, lobe pumps for highly viscous fluids, helical screw pumps, etc.
